“…[18] conducted a sensitivity analysis using Parkland County and its surrounding counties in Alberta, Canada as an example to assess the impact of key techno-economic parameters on the calculation results.Warmadewanthi I.D.A.A. [19] studied the type of biological cover (old and young refuse) and thickness (15, 20, 30 cm) as variables.The results showed that the differences of methane gas and leachate reduction in 15 vs 20 cm bio-cover thickness were significant.…”

Liupanshui city is located in the western part of Guizhou province, the region is extremely rich in coal resources, coal industry is more concentrated, coal mining and processing and other aspects of the solid waste resources if the good use of the city of Liupanshui city will get new development opportunities. The article takes the solid waste resources of coal industry in Liupanshui city as the research object, and uses the hierarchical analysis method to measure and evaluate the factors affecting the comprehensive utilisation of the solid waste resources of coal industry in Liupanshui city. The evaluation results show that the comprehensive utilisation of coal-based industrial solid waste resources in Liupanshui city is affected by the investment amount of solid waste per unit, technological maturity, industrial policy, and friendliness to the atmosphere. Countermeasures are proposed for these four constraints in anticipation of improving the comprehensive utilisation of coal-based industrial solid waste resources in Liupanshui city.

“…Given the low BOD content of mature landfill leachate and the additional operating cost of external carbon sources, it is necessary to identify some cheap and easily available new carbon sources and study their applicability. For example, municipal solid waste will produce a certain amount of methane in the landfill process, and some of them will exist in the landfill leachate in the form of dissolved gas [111,112]. However, this methane is not fully utilized and is mostly discharged into the atmosphere in the form of waste.…”

Nitrogen Removal from Mature Landfill Leachate via Anammox Based Processes: A Review

et al. 2022

View full text Add to dashboard Cite

Mature landfill leachate is a complex and highly polluted effluent with a large amount of ammonia nitrogen, toxic components and low biodegradability. Its COD/N and BOD5/COD ratios are low, which is not suitable for traditional nitrification and denitrification processes. Anaerobic ammonia oxidation (anammox) is an innovative biological denitrification process, relying on anammox bacteria to form stable biofilms or granules. It has been extensively used in nitrogen removal of mature landfill leachate due to its high efficiency, low cost and sludge yield. This paper reviewed recent advances of anammox based processes for mature landfill leachate treatment. The state of the art anammox process for mature landfill leachate is systematically described, mainly including partial nitrification–anammox, partial nitrification–anammox coupled denitrification. At the same time, the microbiological analysis of the process operation was given. Anaerobic ammonium oxidation (anammox) has the merit of saving the carbon source and aeration energy, while its practical application is mainly limited by an unstable influent condition, operational control and seasonal temperature variation. To improve process efficiency, it is suggested to develop some novel denitrification processes coupled with anammox to reduce the inhibition of anammox bacteria by mature landfill leachate, and to find cheap new carbon sources (methane, waste fruits) to improve the biological denitrification efficiency of the anammox system.

“…Post-mining soil and solid waste sampling were carried out randomly on non-intact, disturbed soil. Samples were taken at 7 locations, at depths of 0, 20, and 50 cm, with as much as 0.5 kg being recovered each time (Susianti et al, 2022;Warmadewanthi et al, 2021a). The samples from different depths were mixed and placed in double plastic, then labeled with the date of collection, place of collection and code.…”
